Forex spread betting versus "normal" trading.

Can anyone inform me of the main differences of trading Forex normally,versus through a spread betting provider.
The no TAX element of spread betting is hugely appealing to me,but i have only ever traded forex(or anything else) "normally".
Is it more or less the same,are the spreads much different,any advice from someone that trades via spread betting would be much appreciated.

Think the spreads are a bit bigger so it's determined by your trading style and preference.

Obviously in the UK its tax free so if you're making big money then its better paying a bigger spread to avoid tax. Also, you can always use mt4 demo for charting
